Hey Wardie,

Definitely exciting times for PYM at the moment. Only a few more days and hopefully we'll get confirmation of flow rates in the thousands!

My understanding of this well is that they will not be using hydraulic fracturing as there are already fracture systems through the Austin Chalk that they have deliberately targeted and drilled through to increase their chances of achieving higher production rates with a slower rate of decline.

The water pumped into and now out of the well is used maintain pressure during the perforation of the casing. Because they are not using hydraulic fracturing the pressure inside the well during perforation would have been less than that in the formation (due to oil and gas under pressure), so that any debris would then flow back into the well rather than block up the formation and decrease the future flow rate. The debris would then hopefully be pumped out with this load water. During hydraulic fracturing the well pressure would be higher than the formation pressure, such that after perforation the frac fluids are injected into the formation and open up fractures for oil/gas to flow into the well.

If the well doesn't flow at the expected rate, then they sometimes use an acid treatment to attempt to dissolve the debris and compacted rock caused by the perforation and hopefully allow a greater surface area for oil/gas to flow into the well.

Anyways, rambled again....

Cheers,
